WARNING
ELECTRIC GROUNDING INSTRUCTIONS
This appliance (120V ovens only) is equipped with a three-prong (grounding) plug for your protection against shock
hazard and should be plugged directly into a properly grounded three-prong receptacle. Do not cut or remove the
grounding prong from this plug..
NOTICE
This appliance, when installed, must be electrically grounded in accordance with local codes, or in the absence of local
codes, with the National Electrical Code, ANSI/NFPA 70 or the Canadian Electrical Code, CSA C22.2, as applicable.
Wiring diagrams are located on the side of the control panel assembly, as well as in this manual (beginning on Figure 10)
.
Be sure that the input voltage and phase match the requirements shown on the serial plate, which is located inside the
lower front panel.
Ovens ordered to operate on 120V power have a three-wire cord. (Double-deck ovens have two power cords, one for
each oven.) Each cord has a three-prong plug that fits any standard three-prong grounded receptacle. Single-oven units
require a 15 ampere supply, while double-oven units require a 20 ampere supply. (120V ovens shipped to Canada do
NOT have factory installed power cords, and must be wired as described below.)
Ovens without a power cord have a terminal block. The electric supply must be brought through the service panel in the
rear of the oven and connected to the terminal block. See the wiring diagrams in this manual (beginning Figure 10). The
unit must be adequately grounded. Use 167°F (75°C) wire for all supply lines.
Ovens are factory-equipped with a two-pole terminal block, located behind a cover plate located on the rear of the oven.
To connect the supply wires, remove the cover plate, then route the supply wires and the grounding wire through the
strain relief fitting to the terminal block. Insert the supply wires, one each, into the two poles of the terminal block and
tighten the screws. Insert the ground wire into the grounding lug and tighten the screw. Re-attach the cover plate.
Three phase units are wired as above, using only two supply wires. The third wire is not used and must be properly
terminated.
All units are shipped wired as specified by factory order. Conversion between single-phase and three-phase can
be accomplished by referring to phase loading and line amperes chart on wiring diagram for wire size and ampere
requirements.
